Here it can be summed up accurately in two words---hot and dry. But the bees usually manage to produce a summer crop in these conditions. My grandson who has most of his hives in outyards keeps hauling out barrels of water for theem to manage their heat control. My hives, being near my house, have the benefit of water from sprinklers etc.
One new problem we are trying to overcome this year (particularly in my southern location and environs) is the damages from arson that has destroyed many hives and thousands of hectares of foraging land. The summer crop, which is usually larger than the spring crop, is expected to be considerably smaller this year.
